CacheAudit
CacheAudit is a versatile framework for the automatic, static analysis of cache side channels. CacheAudit takes as input a program binary and a cache configuration, and it derives formal, quantitative security guarantees for a comprehensive set of side-channel adversaries, namely those based on observing cache states, traces of hits and misses, and execution times.
Our technical contributions include novel abstractions to efficiently compute precise overapproximations of the possible side-channel observations for each of these adversaries. The results we obtain exhibit the influence of cache size, line size, associativity, replacement policy, and coding style on the security of the executables, and include the first formal proofs of security for implementations with countermeasures such as preloading and data-independent memory access patterns.
